Crys.m is a MATLAB routine that combines a micrograph of a crystal with a scaleable, rotatable three-dimensional cage structure to determine the orientation of the crystal axes. The example presented here uses the morphology of tetragonal lysozyme. Rotation of the cage until it aligns with the crystal in the image yields the orientation of the c axis of the crystal relative to the image normal. This analysis can be used for quantitative determination of crystal orientation effects induced by electric, magnetic and/or gravitational fields.

A numerical method is introduced to determine the nuclear magnetic resonance frequency of a donor (P-31) doped inside a silicon substrate under the influence of an applied electric field. This phosphorus donor has been suggested for operation as a qubit for the realization of a solid-state scalable quantum computer. The operation of the qubit is achieved by a combination of the rotation of the phosphorus nuclear spin through a globally applied magnetic field and the selection of the phosphorus nucleus through a locally applied electric field. To realize the selection function, it is required to know the relationship between the applied electric field and the change of the nuclear magnetic resonance frequency of phosphorus. In this study, based on the wave functions obtained by the effective-mass theory, we introduce an empirical correction factor to the wave functions at the donor nucleus. Using the corrected wave functions, we formulate a first-order perturbation theory for the perturbed system under the influence of an electric field. In order to calculate the potential distributions inside the silicon and the silicon dioxide layers due to the applied electric field, we use the multilayered Green's functions and solve an integral equation by the moment method. This enables us to consider more realistic, arbitrary shape, and three-dimensional qubit structures. With the calculation of the potential distributions, we have investigated the effects of the thicknesses of silicon and silicon dioxide layers, the relative position of the donor, and the applied electric field on the nuclear magnetic resonance frequency of the donor.

At the beginning of the 80s new approaches to translation were emerging in such a way that, in the global context of postmodernism and poststructuralism, they provoked a reassessment of Translation Studies (TS), acknowledging ideologies as a relevant concept to TS and considering the political and visible role of the translator. This introduction aims to establish a basic theoretical framework in which we can develop an analysis of the ‘alterations’ that, consciously or unconsciously, translators have imposed on Le deuxième sexe (1949, Gallimard) by Simone de Beauvoir for the last fifty years. Furthermore, it is essential to examine the divergences of the censoring attitude adopted by the first male translators (Parshley, Palant and Milliet) who considered this text to be a sex manual, and the one adopted by more recent female translators (Martorell and Simons) who considered it to be a philosophical book on feminism. Nevertheless, despite this tendency to consider that translators are the only professionals responsible for the translation process, it is necessary to bear in mind the work carried out by the paratranslator, who is the real censor and ‘decider’ of the way a work is presented to the translation community. Paratranslators work with paratexts (also known as ‘analysis-spaces’), and this makes it possible to study the ideological adaptation that a cultural object undergoes when it is incorporated into a new culture and society (covers, volumes, tables of contents, titles, iconic or visual elements and so forth). In short, the analysis of the texts and paratexts of Le deuxième sexe, along with its subsequent translations and rewritings into Spanish, Portuguese and English, will help reveal the function of the censoring apparatus and demonstrate the essential role that –without exception– ideologies play in the professional work of translation and paratranslation, since they have a decisive influence on the reception of the cultural (and ideological) object, in both the society in which it is created and that in which it is received.

Purpose – The paper assesses the extent to which China’s comparative advantage in manufacturing has shifted towards higher-tech sectors between 1987 and 2005 and proposes possible explanations for the shift. Design/methodology/approach – Revealed comparative advantage (RCA) indices for 27 product groups, representing high-, medium and low-tech sectors have been calculated. Examination of international market attractiveness complements the RCA analysis. Findings for selected sectors are evaluated in the context of other evidence. Findings – While China maintains its competitiveness in low-tech labour intensive products, it has gained RCA in selected medium-tech sectors (e.g. office machines and electric machinery) and the high-tech telecommunications and automatic data processing equipment sectors. Evidence from firm and sector specific studies suggests that improved comparative advantage in medium and high-tech sectors is based on capabilities developing through combining international technology transfer and learning. Research limitations/implications – The quantitative analysis does not explain the shifts in comparative advantage, though the paper suggests possible explanations. Further research at firm and sector levels is required to understand the underlying capability development of Chinese enterprises and the relative competitiveness of Chinese and foreign invested enterprises. Practical implications – Western companies should take account of capability development in China in forming their international manufacturing strategies. The rapid shifts in China’s comparative advantage have lessons for other industrialising countries. Originality/value – While RCA is a well-known methodology, its application at the disaggregated product group level combined with market attractiveness assessment is distinctive. The paper provides a broad assessment of changes in Chinese manufacturing as a basis for further research on capability development at firm and sector levels.
